Special Issue Information

Dear Colleagues,

It is a great pleasure to invite you to the second edition of the Special Issue: Applied Catalysis in Chemical Industry: Synthesis, Catalyst Design, and Evaluation. The significant economic and strategic importance of catalysis makes it a rapidly evolving field. In the face of the present day’s significant challenges, it is essential to acquire fundamental knowledge about the structures and phenomena of the surfaces of catalysts as well as the relationships between the composition, synthesis method, properties, and performance of catalysts in industrial processes. Research is still needed to improve existing catalysts or design new systems which may efficiently and selectively conduct a given reaction toward the desired product.

This Special Issue is devoted to the design and characterization of heterogeneous catalytic systems for industrial chemical processes. The aim is to collect papers presenting the current state of knowledge, indicating areas requiring further research, and showing the direction of ongoing development work. Contributions in the form of original research articles, short communications, perspective articles, and review articles reflecting the progress in the proposed topics are welcome. The main focus will be on comprehensive experimental studies of synthesis, characterization, and evaluation of catalyst performance in industrial processes. The proposed topics include, but are not limited to, the following:

  • methane conversion;
  • water–gas shift reaction;
  • ammonia synthesis;
  • ammonia decomposition;
  • ammonia oxidation;
  • carbon oxides methanation;
  • selective catalytic reduction of nitrogen oxides;
  • N2O decomposition;
  • hydrogen production processes.

The scope also includes an investigation of catalysts under conditions close to the industrial ones, a comparison of the studied catalytic systems with the currently operating commercial systems, and a demonstration of the validity of their application in a given chemical process.

CuO/ZnO/Al2O3 catalysts are commonly used for the methanol steam reforming reaction. The oxalate precursor of CuO/ZnO/Al2O3 catalysts were prepared via the co-precipitation method using oxalic acid as the precipitator, deionized water and ethanol as the solvent, and microwave radiation and water baths as aging heating methods, respectively. This suggests that ethanol selects the crystalline phase composition of oxalate precursors and limits their growth. Microwave irradiation prompted the isomorphous substitution between Cu2+ of CuC2O4 and Zn2+ of ZnC2O4 in the mother liquid; Zn2+ in ZnC2O4·xH2O was substituted with Cu2+ in CuC2O4, forming the master phase (Cu,Zn)C2O4 in the precursor. Moreover, the solid solution Cu-O-Zn formed after calcination, which exhibited nano-fibriform morphology. It has the characteristics of small CuO grains, a large surface area, and strong synergistic effects between CuO and ZnO, which is conducive to improving the catalytic performance of methanol steam reforming. The conversion rate of methanol reached 91.2%, the space time yield of H2 reached 516.7 mL·g−1·h−1, and the selectivity of CO was only 0.29%. Full article

The production of ammonia through the Haber–Bosch process is a large-scale catalytic industrial endeavour with substantial energy consumption. A key area of energy optimisation for this process involves efforts to ease the synthesis reaction conditions, particularly by reducing the operating pressure. To achieve this goal, new catalysts are designed to function effectively at lower pressures and temperatures. In recent years, reports in the literature concerning including lanthanide oxides in the catalysts’ composition have started appearing more frequently. This review article offers a concise overview of the pivotal role that lanthanide oxides play in the field of ammonia synthesis catalysts. The paper delves into the diverse utilisation of lanthanide oxides, emphasising their role in catalytic systems. The review explores recent advances in the design of catalysts incorporating lanthanide oxides as promoters or support materials, highlighting their impact on enhancing catalyst stability, activity, and operation. Three main groups of catalysts are discussed, where iron, ruthenium, and cobalt constitute the active phase. Insights from recent research efforts are synthesised to provide a comprehensive perspective on the application prospects of lanthanide oxides in ammonia synthesis catalysts. Full article
